第二种方案：

<template>
  <div class="drawer">
    <button @click="clickBtn">点击</button>

    <div class="background" v-if="open" @click.self="closeDrop">
      <div class="drop" :class="{ active: isActive, close: isClose }">drop</div>
    </div>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  props: {},
  data () {
    return {
      open: false,
      isActive: false,
      isClose: false
    }
  },
  methods: {
    clickBtn () {
      this.open = true
      this.isActive = true
      this.isClose = false
    },
    closeDrop () {
      this.isClose = true
      setTimeout(() => {
        this.open = false
      }, 200)
    }
  }
}
</script>

<style scoped lang="scss">
  .background {
    position: fixed;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background: rgba($color: #000000, $alpha: 0.5);
    .drop {
       0px;
      position: absolute;
      top: 0;
      right: 0;
      bottom: 0;
      background: #fff;
    }
    // 开
    .active {
      animation: opendoor 0.3s normal forwards;
    }
    @keyframes opendoor {
      from {
         0;
      }
      to {
         45%;
      }
    }
    // 关
    .close {
      animation: close 0.3s normal forwards;
    }
    @keyframes close {
      0% {
         45%;
      }
      100% {
         0;
        opacity: 0;
      }
    }
  }
